原理说明

利用SurfaceView预览视频
利用系统自带的MediaRecorder实现短视频app源码中短视频视频的录制

实例化
设置音频输入
设置输出格式
设置视频编码格式
设置输出路径
调用prepare()进行资源初始化
调用start()开始录制
注意： 这里的步骤先后顺序非常重要，如果对MediaRecorder不是那么熟悉，还是照着步骤写比较好

使用方法

    // 录制视频private void toRecordVideo() {RecordConfig.getInstance().with(this).setQuality(RecordConfig.Quality.QUALITY_480P).setMaxDuration(6*1000).setFocusMode(RecordConfig.FocusMode.FOCUS_MODE_CONTINUOUS_VIDEO).setOutputPath("/smallvideo/").obtainVideo(REQUEST_CODE_VIDEO);}@Overrideprotected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {super.onActivityResult(requestCode, resultCode, data);if (requestCode==REQUEST_CODE_VIDEO&&resultCode==RESULT_OK){//接收视频输出路径String videoPath=RecordConfig.obtainVideoPath(data);int duration=RecordConfig.obtainVideoDuration(data);Log.i(this.getClass().getSimpleName(),"obtainVideoPath="+videoPath+" duration="+generateTime(duration));}}
